Is it common for people with pernicious anemia to go on to develop thyroid problems? I have had pernicious anemia for seven years no and over time it feels like the b12 hasn't been working with my symptoms. Between the age of 20-23 I was just having the regular three month b12 shot from the GP but from the age of 23-27 I have been self injecting with the help of this forum. No matter how much b12 I seem to inject I never feel "right" in myself and I have just lost the will to do anything remotely active.
My sister has recently been diagnosed with pernicious anemia at the age of 22 which is similar to me at 20. She said she feels really weak and her iron was at a low of 22 when she first went to the GP but they said it was fine, it was only after she went back and it was at 7 they said that she needed tablets. I am wondering if it has been lack of iron making me feel this way as she has been shedding hair and has gone early grey and those are two of my physical symptoms.
The GP always told me my iron was "good" whatever that means and I am worried that if I leave this for too long I will just wither away. I am injecting hydroxoB12 once a week sometimes twice it just seems to do nothing.
Could it be lack of iron just like my sister as it would possibly run in the family or mayb an underlining thyroid problem? I am not sure if pernicious anemia can cause thyroid issues or low iron as not one GP has ever mentioned this to me.
